Brennan Benson 51aab1c793 fix(terminal): harden macOS login-preflight spawn path (#9301 follow-ups) (#9606)
* fix(terminal): harden macOS login-preflight spawn path (#9301 follow-ups)

Follow-ups to the #9301 two-pass review. Re-derived severities: none are
release blockers; these are low-likelihood robustness/observability fixes.

F1 macos-tcc-login-shell: only cache a conclusive PAM verdict. A probe our
own SIGKILL timeout / ETIMEDOUT / maxBuffer killed proves nothing about PAM,
so it no longer sticks the whole process into direct-spawn — it fails open
for that spawn, re-probes next time, and self-heals once PAM answers.

F2 daemon-entry: prepareMacosTccLoginShell returns the outcome; the daemon
emits a structured macos-login-preflight {ok, reason} log on degrade, since
detached daemons destroy stderr and lose the console.warn.

F3 local-pty-provider: an atomic guard before the tracking write coalesces a
concurrent same-session-id spawn onto the winner instead of orphaning an
untracked, unkillable PTY.

F4 daemon-server: preparations carry their clientId; a control-socket close
cancels only that client's pending preps, so a mid-preflight disconnect no
longer leaves a durable orphan daemon PTY.

F7 warm the PAM probe at daemon startup (mirrors warmPwshAvailabilityCache);
note the pipe-vs-PTY probe fidelity limit; test that kill with no pending
prep still surfaces SessionNotFoundError.

Deliberately skipped F5 (self-limits to next reload; a real fix needs
speculative in-flight-generation tracking) and F6 (inherent to legacy
v22 attach; self-heals once daemons are v23).

* fix(terminal): bound preflight recovery work

* fix(terminal): cancel preflight when daemon stream closes

Brennan Benson 64be819790 fix(runtime): harden watcher and PTY teardown ownership (#8661)
* fix(runtime): retain watcher and PTY teardown ownership

* fix(runtime): restore watchers after interrupted cleanup

* fix(runtime): prevent stale watcher revival

* test(runtime): cover watcher shutdown ownership

* test(daemon): model physical PTY exit

* fix(daemon): keep shutdown terminating when disposal cannot prove exit

A rejecting host.dispose() (unreapable child past its exit deadline) left
the shutdown RPC without its process.nextTick(shutdown) and skipped socket
cleanup in shutdown(), stranding the daemon as an unreachable orphan after
the stale-daemon replacement flow unlinks its socket. Log and continue:
daemon exit reparents the child to init instead of blocking on it.

* fix(runtime): keep local watching alive after an idle-kill deadline miss

An idle child that outlived the exit deadline set shutdownRequested on the
shared desktop supervisor, which has no retire-and-replace path — every
later subscribe rejected supervisor_disposed and the roots were cached
unwatchable, silently ending local file watching for the session. The idle
path owns zero records, so there is no double-watch hazard; the zombie
keeps its capacity reservation until physical exit and the next subscribe
gets a fresh child.

* fix(renderer): resync replayed paired-web file watches

Transparent replay removed the implicit resync the old close-and-rebuild
path provided: a replayed files.watch only reports changes from its own
native setup, so changes during the reconnect gap were silently lost.
Deliver a conservative overflow to consumers once the replayed watch is
ready, matching the overflow-after-interruption contract everywhere else.

* fix(runtime): address teardown review findings

* fix(runtime): retry watches after teardown deadlines

* Fix PTY descendant leaks on forced teardown

* Fix jitter-sensitive terminal lifecycle test

Brennan Benson 40d0159926 fix(terminal): kill agent descendant processes on session teardown (STA-1800) (#8706)
* fix(terminal): kill agent descendant processes on session teardown (STA-1800)

Agent CLIs spawn tool children in detached process groups that PTY
SIGHUP can never reach. Killing an agent session (tab close, retire,
sleep) left those children running as orphans — eight orphaned git
processes burned ~8 cores for up to 11.5h under the agents-running
keep-awake and drained a battery to 8%.

New pty-descendant-termination module: snapshot the ppid tree BEFORE
signalling (a dead root's descendants reparent to pid 1 and become
unfindable), SIGTERM the root group and every descendant, then after a
2s grace SIGKILL survivors gated on a pid+start-time identity re-check
so a recycled pid is never signalled. Snapshot is bounded and never
rejects; failures degrade to today's shell-only kill.

Wired for agent sessions only (plain terminals keep nohup semantics) at
all three POSIX kill sites: local provider shutdown, daemon
TerminalHost immediate kill (the pty:kill path — force-kill bypassed
Session.kill entirely), and daemon Session graceful kill.

Verified live in the built app: an agent pane with a detached-pgid
child; the child survived on the unwired build (three control runs) and
dies within ~5s with the fix. Windows ConPTY and SSH-hosted PTYs keep
the previous foreground-tree contract (documented follow-ups).

b902f19b0d fix(terminal): send CSI-u Shift+Enter to Droid on Windows (#7620) (#7668)
* fix(terminal): send CSI-u Shift+Enter to kitty TUIs (droid) on Windows (#7620)

On Windows, Shift+Enter was always sent as the Alt+Enter byte ESC+CR (added in
#2418 for Codex, which reads win32-input-mode and ignores CSI-u). droid speaks
the kitty keyboard protocol, parses CSI-u directly, and treats ESC+CR as a plain
Enter — so Shift+Enter SUBMITTED the message instead of inserting a newline.
droid works in other terminals (Windows Terminal, Warp) because those honor
win32-input-mode / kitty; Orca (xterm.js) withholds kitty from local Windows
ConPTY panes and emits neither.

Make the Windows Shift+Enter byte pane-aware: latch whether a pane's program
advertised the kitty keyboard protocol (query CSI ? u, push CSI > .. u, or set
CSI = .. u) and send CSI-u (\x1b[13;2u) to those panes, keeping the
Codex-compatible ESC+CR for win32-input-mode-only TUIs. Non-Windows is unchanged
(always CSI-u).

Verified end-to-end against the real droid and Codex CLIs through the actual
production functions: droid now newlines, Codex still newlines.

* fix(terminal): route Windows Shift+Enter safely for Droid

e84a8ddec9 Terminal performance initiative: pipeline fixes + term-speed-2 revival + PTY flow control (integration branch) (#7214)
* Skip legacy hidden skip grammar assertions

* Fix hidden TUI snapshot test setup

* Fix sleep wake history test contract

* Fix hidden delivery startup gate helper

* Fix hidden Latin skip branch predicate

* Fix hidden synchronized split-boundary replay

* Stabilize remote runtime mixed subscription test

* Keep hidden startup query parser active during window

* Stabilize raw emoji golden restore width

* Stabilize raw emoji golden fixture completion

* Keep terminals responsive under agent output load

* Add frozen-terminal repro harness and silent-drop regression tests

Investigation harness for the frozen-terminal reports (Discord
#performance, issue #2836): pane shows content, shell alive, daemon
output.log flat while typing.

- e2e: renderer crash -> auto-reload recovery and three restart/restore
  shapes (live daemon, SIGSTOP-wedged daemon, daemon killed between
  launches), each probing input at both drop layers. Post-crash phases
  drive the renderer from the main process because a crashed target
  severs Playwright's CDP session even though the app recovers.
- e2e helpers: layer-discriminating probes (direct pty.write vs
  transport input, plus pty:listSessions ownership-rebuild revival).
- unit repro: vendored xterm 6.1.0-beta.287 WriteBuffer permanently
  wedges when a sync throw escapes a write-completion callback or a
  custom parser handler (xterm-write-buffer-stall.repro.test.ts).
- unit repros for both silent input-drop layers: main drops writes for
  a live PTY once ptyOwnership loses the id (revived by listSessions),
  and the renderer transport stays unbound after a failed connect.
- pty.test.ts: unregister every leaked SSH provider id in afterEach so
  module-level provider state cannot leak across tests.

* Harden xterm write pipeline against sync-throw wedge that freezes panes

A synchronous exception escaping xterm's WriteBuffer loop permanently
wedges that terminal: _innerWrite has no try/catch around the parse
action or the write-completion callback, the tail re-schedule never
runs, and write() only re-arms on an empty buffer. The pane stops
rendering and, if a replay was in flight, the replay guard latches and
pty-connection's onData silently eats every keystroke — matching the
field reports (Discord #performance, issue #2836: content visible,
shell alive, daemon output.log flat). Both vectors verified against
vendored xterm 6.1.0-beta.287 in xterm-write-buffer-stall.repro.test.ts.

Three layers of defense:
- Guard every write-completion callback Orca hands xterm at the two
  choke points (writeForegroundTerminalChunk, writeBackgroundTerminalChunk),
  with settle and onParsed guarded separately so a WebGL/renderer
  failure during viewport settle cannot starve the replay-guard release.
- Guard all throwing-capable custom parser handlers (DA1, OSC 10/11,
  CSI ?h/?l mode reports, OSC 52 clipboard, OSC 7 cwd), degrading a
  throw to "not handled" — same escape class as
  terminal-link-provider-guard.ts.
- Replay-guard watchdog: each engagement releases exactly once, from
  xterm's completion or a 10s watchdog, so a lost completion (wedged
  pipeline, disposed-terminal race) cannot latch the guard on a live
  pane; replayIntoTerminalAsync resolves on either path so restore
  chains cannot hang. Force-releases record a crash breadcrumb.

All guard trips record rate-capped crash breadcrumbs, so the next field
occurrence names the throwing stack instead of failing silently.

* Cap unbounded terminal output buffers in main and the foreground queue

Field evidence (Discord #performance / #2836): renderer memory climbs to
~1.5 GB and terminals freeze; a force reload does not help until memory
recovers. Two unbounded buffers matched that shape:

- Main-process pendingData grew by string concatenation without bound
  while the renderer could not receive (frozen, starved, mid-reload) —
  main-heap bloat a renderer reload cannot clear. Now capped at 2 MB per
  PTY: past the cap the buffered bytes are dropped and the entry stays
  O(1) until the renderer ACKs again, then a droppedOutput sentinel is
  delivered and the pane repaints from the authoritative main-owned
  buffer snapshot (existing hidden-output restore path) instead of
  continuing a stream with a silent gap.
- The renderer output scheduler capped only hidden-pane backlogs; the
  foreground path could queue a visible pane's flood without bound when
  the drain could not keep up. The 2 MB cap now applies to every
  foreground enqueue branch too, with a foreground-specific skip notice.

Verified: new main-side cap test (starve → flood → sentinel → normal
flow resumes), renderer sentinel-to-snapshot-restore test, two
foreground scheduler cap tests; full pty/terminal-pane/pane-manager
suites (1981 tests) and typecheck pass.

* Make replay-guard stall release probe-certified instead of time-based

The previous stall watchdog blindly released the input guard after 10s.
If a replay were genuinely still parsing on a starved machine, that
early release could leak xterm's auto-replies into the shell — and into
agent TUIs, where a leaked ESC reads as the user pressing Escape.

Replace the blind release with a probe: when a completion looks
overdue, enqueue an empty write behind the replay. xterm parses writes
in order, so every outcome is provably safe:
- probe parses after the replay completion ran: normal release already
  happened; probe is a no-op.
- probe parses but the replay completion never ran: all replay bytes
  have parsed, no further auto-replies can exist — the completion was
  genuinely lost. Release + breadcrumb.
- probe never parses (bounded wait): the pipeline is wedged, and a dead
  parser can never emit auto-replies, so releasing cannot leak input.
  Release + breadcrumb naming the pane as needing recovery.
While the probe is pending — a slow-but-alive replay — the guard now
HOLDS instead of releasing early; that case is pinned by a regression
test.

* Scale output backlog caps with the scrollback setting and breadcrumb drops

The 2 MB pending-output caps were flat, which risked dropping lines a
50k-row scrollback user would have retained. Both caps (main pendingData
and the renderer output queue) now derive from one shared policy:
max(2 MB, scrollbackRows x 120 chars) — 2 MB at the 5k default, 6 MB at
the 50k max. The main side reads the setting live via getSettings; the
renderer scheduler is configured where the terminal lifecycle already
reads the scrollback setting.

Every drop now records a rate-limited crash breadcrumb with dropped and
cap sizes (terminal_output_backlog_dropped in the renderer,
terminal_pending_output_dropped in main — no pty ids, session ids can
embed workspace paths). Field drop frequency and size decide whether the
cap constants need raising, replacing theory with data (#2836, #7017).

Backlog skip notices are now cap-agnostic since the limit varies.

* Extract breadcrumb recording into a collection-safe leaf module

Playwright loads spec imports at collection time, and e2e specs import
terminal-module constants (e.g. terminal-attention.spec.ts pulls
POST_REPLAY_MODE_RESET from layout-serialization, whose chain reaches
replay-guard). The breadcrumb import added to the terminal modules made
that chain reach crash-diagnostics.ts, whose top-level import.meta.hot
and webview-registry import crash Playwright's transform
("ReferenceError: exports is not defined in ES module scope") — every
e2e shard failed at collection before running a single test.

Move recordRendererCrashBreadcrumb into crash-breadcrumb-recorder.ts
(type-only imports, no import.meta) and point the terminal modules and
their test mocks at it; crash-diagnostics re-exports for existing
callers. Full e2e suite collects again (262 tests / 94 files); unit
suites, typecheck, lint green. No runtime behavior change.

* Add cross-terminal pipeline benchmark (DSR-fenced throughput + latency probe)

Run inside any terminal (Orca pane, iTerm2, Ghostty, Terminal.app, VS Code)
to measure its full byte path. DSR round-trip latency at idle and under a
paced agent-TUI load, plus fenced throughput over four deterministic
fixtures. The DSR fence forces 'all bytes parsed' before the clock stops so
xterm.js-class ingest queues can't flatter the result.

First piece of the terminal performance initiative's measurement rig.

findings, workstreams (baselines, #7153 validation, term-speed-2 revival

baseline-relative success criteria.

* Add cross-terminal baseline results (Orca 1.4.91 prod vs Terminal.app vs Ghostty)

Headline: Orca DSR latency under 1MB/s agent-TUI load is p50 134ms / p99 292ms
vs 0.45ms (Terminal.app) and 0.21ms (Ghostty). Idle latency is fine (0.69ms
p50) — the problem is queueing under load, not the pipeline hop. agent-tui
fenced throughput: Orca 2.0 MB/s vs Terminal.app 37 MB/s, Ghostty 78 MB/s.

* Add pipeline-loss decomposition benches (headless xterm + daemon ingest)

Both isolate layers of the 51x agent-tui gap found in baseline-jul02:
bare @xterm/headless parses agent-tui at 103 MB/s and daemon Session
ingest (emulator + pending-output recording + fanout) at 103 MB/s —
on the byte stream the full Orca pipeline delivers at 2.0 MB/s.
Parser and daemon are exonerated; the loss is in main per-chunk
processing, delivery/ACK pacing, or renderer layers above xterm.

* Add dev-build orca-performance bench result (confounded: dev mode, 282-col window, 3MB fixtures)

DSR under load p50 161ms — the #7139/#7150 branch does not move the
under-load latency class. Expected in hindsight: DSR replies are ordered
within the output stream, so the metric measures output-queue depth;
cooperative drain paces input responsiveness but cannot reorder the queue.
Shrinking the queue itself (producer flow control, task 6) and raising
agent-tui throughput (task 9) are the levers for this number.

* Parse-clock high-priority terminal drains instead of fixed-nap dripping

Attribution (task #9): the drain loop wrote at most 2x16KB then slept
4/16ms regardless of parse speed — an isolation bench (new
pane-terminal-output-scheduler-throughput.bench.test.ts) measures that
drip at 1.9 MB/s background / 27 MB/s foreground against xterm's
~103 MB/s parse rate, matching the baseline-jul02 end-to-end numbers
(agent-tui 2.0 MB/s in prod 1.4.91).

Fix: high-priority (visible-pane) drains now re-arm on xterm's
parse-completion callback and carry 8 writes per tick; the isolation
ceiling rises 27 -> 117.6 MB/s (parse-limited). Background cadence is
deliberately unchanged (2 MB/s drip protects the focused pane; hidden
delivery is term-speed-2's job). DRAIN_TIME_BUDGET_MS still bounds
per-tick work, preserving #7139's cooperative-drain intent.

Validation: 621 scheduler/guard/pty tests green, typecheck clean.

* Findings: 51x loss attributed to O(tail) retained-tail redraw path in main onPtyData

Co-authored-by: Orca <help@stably.ai>

* Window the retained-tail redraw path to the cursor's reach

Attribution (findings log 2026-07-03): main's onPtyData consumed ~93% of
the event loop under an agent-TUI flood, and the dominant term was
appendNormalizedToMultilineTailBuffer + finalizeRetainedTerminalRows
materializing ~2x tail-length row objects plus a per-row trailing-space
regex on every chunk — 0.888ms/chunk at the 2,000-line cap, on every
Claude-Code-shaped frame (cursor-up + erase-below).

The multiline algorithm now runs on a suffix window sized by the chunk's
maximum upward cursor excursion (plus the inherited redraw cursor and a
safety margin); the untouched prefix is shared by reference with a cheap
last-char trailing-space check to match the reference trim. Pathological
full-height cursor-ups fall back to the unwindowed implementation, which
is kept verbatim and exported as the reference for the 500-case
differential fuzz (retained-tail-redraw-window.equivalence.test.ts).

Micro-bench at a full 2,000-line tail: 0.888 -> 0.073 ms/chunk (12x).
1,415 runtime tests green, typecheck clean.

Co-authored-by: Orca <help@stably.ai>

* Throttle the terminal wait-blocked check off the PTY hot path

Post-windowed-tail attribution (findings log 2026-07-03): the blocked-
reason complex — two full-tail buildTerminalWaitText builds plus
toLowerCase and multi-pattern scans per chunk, existing only to stamp
waitBlockedAt — consumed ~85% of onPtyData's remaining cost (~700-790ms/s
under an agent-TUI flood).

The check now runs at a 50ms cadence over coalesced chunks (PTY chunk
boundaries are arbitrary, so coalescing preserves semantics), with a
trailing-edge timer so burst-final state is always evaluated, and an
immediate bypass when the incoming chunk (plus a 31-char split carry)
contains a prompt keyword — so actionable-prompt stamping stays
per-chunk-immediate while keyword-free flood frames skip the complex
entirely. Previous wait text is cached per pty instead of rebuilt, and
state is cleared at both pty teardown sites.

1,415 runtime tests green (including the cross-chunk prompt test, which
exercises the keyword bypass), typecheck and lint clean.

positive micro-optimization on the daemon per-chunk path; 641 daemon tests

* Add producer-side PTY flow control (watermarks + protocol v19)

Main now pauses the actual PTY when a pane's renderer-pending backlog
crosses the 256KB high watermark and resumes once it drains below the
32KB low watermark (wide hysteresis band so a draining queue cannot flap
pause/resume per flush slice). node-pty pause() stops the pty fd read, so
the kernel/ConPTY buffer fills and a flooding shell blocks on write —
flood-induced buffered lag becomes shell blocking instead of unbounded
main-process buffering (terminal-performance-initiative §5).

Transport: new fire-and-forget pausePty/resumePty daemon notifications
(protocol v19; 18 added to PREVIOUS_DAEMON_PROTOCOL_VERSIONS), routed
DaemonServer -> TerminalHost -> Session -> subprocess pause()/resume().
LocalPtyProvider pauses node-pty directly. Router/degraded providers
forward; IPtyProvider gains optional pauseProducer/resumeProducer.

Safety invariants:
- Lost-resume failsafe: daemon Session auto-resumes 5s after a pause with
  no matching resume; main re-asserts the pause at most once per 5s while
  still above the high watermark, so a lost resume can never wedge a shell
  and a sustained flood stays throttled.
- Resume on every teardown path: Session kill/exit/dispose/detach; main
  releases on pty exit and on window-destroyed bookkeeping wipes; the
  adapter owes paused sessions a resumePty on the next connect after a
  socket drop.
- Providers without support (SSH relay, legacy protocol <= v18) no-op
  silently, and the scrollback-scaled pending-output cap still bounds
  main memory when pause is unavailable.
- Kill switch: PRODUCER_FLOW_CONTROL_ENABLED in ipc/pty.ts flips the
  whole mechanism off in one line.

daemon-errors.ts is split out of types.ts to stay under the max-lines cap.

Tests: watermark transitions/hysteresis/re-assert (controller unit),
lost-resume failsafe + resume-on-kill/exit/dispose/detach (session),
notification routing + v18 gating + reconnect owed-resume (adapter),
direct pause/resume (local provider), and a flood test asserting pause
fires once, pending stays bounded at HIGH + one chunk, and resume fires
once after drain (ipc/pty).

* Recover terminal output delivery after system sleep

Root cause: main gates every pty:data send on a global + per-PTY
in-flight counter that only renderer ACKs decrement. If ACKs are lost
across a system suspend, the counters pin at the cap and every PTY —
old and newly created — is silently gated forever while output piles up
in pendingData. A focus-preserving display wake also fires no renderer
focus/visibilitychange events, so terminal wake recovery (and the WebGL
context-loss latch clear) never runs. Only a renderer reload recovered.

Three fixes:
- ACK-stall watchdog (src/main/ipc/pty.ts): if sends stay gate-blocked
  for 10s with zero ACK progress while the renderer webContents is
  alive, warn once, reset the in-flight delivery counters, and flush
  held pendingData. Armed lazily on the first gate-blocked send and
  disarmed by every ACK, so it can never fire under healthy heavy load.
- Renderer lifecycle reset now also zeroes the in-flight counters — a
  reload/navigation destroys the renderer dispatcher, so outstanding
  ACKs can never arrive and stale counters would gate the new renderer.
- System-resume wake IPC: main relays powerMonitor 'resume' as
  system:resumed to live windows (plus forceRepaint); preload exposes
  ui.onSystemResumed; the terminal wake-recovery hook runs the same
  recovery path as window focus/visibilitychange.

* Schedule zero-delay terminal drains via MessageChannel

Chromium clamps nested setTimeout(0) to ~4ms, stacking dead gaps onto
every parse-clocked drain tick; the explicit 4ms high-priority re-arm
interval added more. A posted message is still a macrotask — input and
paint are serviced between posts — so cooperative yielding survives
without the clamp. Generation-tokened cancellation; vitest keeps the
timer path (fake timers can't advance channel posts) plus a real-timer
smoke test for the channel path. Standing-queue target: VS Code's ~7ms
class (measured us 18.6ms, them 7.18ms, same rig).

At 9% pipeline utilization the DSR-under-load latency is fixed batching
windows, not queue depth (proved by the MessageChannel drain lever
moving nothing). Both hops charged an expected half-window per chunk;
2ms keeps burst coalescing at negligible IPC overhead (~500 msgs/s
worst case vs MB/s payloads).

* Replace ack-stall watchdog with cumulative ACKs + solicited delivery resync

Design review: the 10s blind-reset watchdog decided correctness from a
wall-clock threshold. Rework piece 1 into a deterministic two-part design
(pieces 2 and 3 — lifecycle-reset counter zeroing and powerMonitor wake
IPC — are unchanged):

- Cumulative ACKs (TCP-style): the renderer dispatcher now tracks a
  monotonic per-pty total of processed chars (terminal-pty-ack-gate) and
  sends it on every ACK alongside the legacy per-chunk delta. Main keeps
  per-pty sentChars/ackedChars and max-merges received totals — idempotent
  and reorder-tolerant, so a lost ACK self-heals when any later ACK
  arrives instead of becoming permanent in-flight debt. Provider
  (SSH/daemon) backpressure is credited only the derived delta, clamped,
  never negative. Main tolerates both payload shapes keyed by field
  presence (dev hot-reload can mix renderer/main versions); totals reset
  on pty exit and renderer lifecycle reset on both sides.

- Solicited resync (replaces the blind reset): when new pty data arrives
  while that pty's delivery is fully gated and no probe is outstanding,
  main sends pty:requestDeliveryResync; the renderer replies with its
  cumulative totals and main reconciles via max-merge, then flushes held
  pendingData. Event-triggered, verified-state recovery — no wall-clock
  threshold decides correctness. The only timer is a 5s request/response
  hygiene timeout that clears the outstanding flag and logs one
  diagnostic warn per silent streak; it never mutates counters (a
  renderer that cannot answer has dead IPC — reload is the only cure).

The 10s corrective watchdog is deleted.

- src/shared/terminal-restore-parity-fixture.ts (renderer-parity fixture)

* Suite 1 findings: two new serialize round-trip bugs (B bold-loss, C cursor)

Scanned seeds 1..2000. Beyond the pre-documented serialize wrap-null-cell bug
(A, 27 seeds, tolerated), the fuzz surfaced two NEW real @xterm/addon-serialize
0.15.0-beta.287 round-trip defects, both of which garble a revealed hidden pane:

- Bug B (seeds 435, 770, 1321): serializing a dim cell followed by a bold-only
  cell emits \x1b[1;22m; SGR 22 clears bold too, so restored bold is lost.
  Minimal repro: '\x1b[2mA\x1b[22m\x1b[1mB' -> restored 'B' loses bold.
- Bug C (seeds 454, 1696): a final content row filled to the right margin leaves
  xterm wrap-pending; the serializer's relative cursor restore lands one column
  short. Minimal repro: '0123456789\x1b[3;5H' at cols=10 -> cursor x=3 not x=4.

Both isolated to pure serializer replay (no Orca preamble), confirming upstream.
Parity fixture verified faithful to the renderer pane's buffer options. Each is
pinned as a standalone it.skip repro; full evidence + classification in
notes/garble-fuzz-divergences.md. Seed 113 (handoff's DECSC/DECRC case) does not
diverge on the current harness. No production code changed.

* Suite 2: hidden-reveal seq-reconciliation fuzz + two new snapshot bugs (D, E)

Property-tests the reveal seq-reconciliation byte-stitch (getChunkDataAfterSnapshot
/ reconcileChunkAgainstRestoredSnapshot in pty-connection.ts), mirrored exactly:
N=200 seeded hide/reveal scenarios with a rich agent-TUI hidden prefix snapshot
and an append-only racing tail, chunked with seq/rawLength meta, seq-domain
restarts, unmetered chunks and droppedOutput markers. Asserts snapshot-at-S +
reconciled tail == snapshot-of-everything (seq-neutral) and == always-visible
(end-to-end). Runtime ~5s at 200; FUZZ_ITERATIONS override documented.

Two NEW real snapshot-limitation garbles found while building it, both distinct
from suite 1's serialize bugs and pinned as standalone it.skip repros:
- Bug D: the DECSC saved-cursor register is not serialized. A hidden TUI that
  saves the cursor (ESC 7 / CSI s) and restores it on reveal (ESC 8 / CSI u)
  lands the restore at home. Repro: 'AB\x1b7\x1b[4;10HCD' + '\x1b8X' -> 'XB' vs 'ABX'.
- Bug E: a snapshot taken mid-escape-sequence (a PTY read split an escape) drops
  the partial sequence (it's parser state, not buffer), so the tail's
  continuation renders literal. Repro: 'AB\x1b[3' + 'mCD' -> 'ABmCD' vs 'ABCD'.
  Fired on ~24% of the corpus (tolerated + counted via prefixEndsMidSequence).

The append-only-tail design isolates seq reconciliation from these and the Bug C
cursor cascade. Full evidence + fix directions in notes. No production changes.

* Suite 3: 25-cycle park/reveal drift e2e test

Extends terminal-hidden-view-parking.spec.ts with a deterministic 25-cycle
park->reveal test on a static rich alt-screen TUI frame (box drawing, SGR
colors, wide CJK/emoji). Baselines against the frame after the first snapshot
restore (so both sides pass through identical machinery — the alt-screen restore
correctly drops normal-buffer scrollback, which is contract not garble), then
asserts every subsequent reveal reproduces it byte-for-byte with no accumulated
drift and no hidden-skip banner. Exercises the real renderer teardown +
HeadlessEmulator snapshot restore + PTY reattach path the fuzz suites model in
isolation. Passes in ~29s (electron-headless, workers=1).

* Fix two serialize round-trip bugs garbling hidden-terminal snapshot restore

BUG B (addon patch): @xterm/addon-serialize's SGR diff emitted bold/dim set
params before the shared intensity reset 22, so "1;22" wiped a freshly set
bold and a bare "22" dropped a still-set bold/dim. Patched via pnpm
patchedDependencies (config/patches) to diff bold+dim as one intensity
group with the clearing 22 emitted first. Other flag pairs (4/24, 3/23,
7/27, ...) have dedicated resets and were verified unaffected.

BUG C (Orca-side hardening): the addon restores the cursor with relative
moves computed from where it assumes replay leaves the cursor; a final row
filled exactly to the right margin leaves replay wrap-pending and the
restore lands one column short. New shared
serializeWithAbsoluteCursor appends an absolute CUP from the source
terminal's authoritative cursor at every restore/replay serialize site
(daemon/runtime HeadlessEmulator.getSnapshot, renderer mobile snapshot
serializer, shutdown layout capture). It skips empty snapshots and
wrap-pending sources so it never changes already-correct behavior.

Round-trip repros + non-regression coverage in
src/main/daemon/terminal-snapshot-serialize-roundtrip.test.ts (verified
failing with the fixes stashed). buildRehydrateSequences extracted to its
own module to keep headless-emulator.ts under the max-lines budget.

* Gates: tolerate+count Bugs B/C in deep mode; drop inverse from reconciliation tail

- Fidelity suite: add snapshotHasSelfCancellingBoldReset (Bug B) and
  isMarginWrapPendingCursorOffByOne (Bug C) predicates so the corpus tolerates +
  counts them like Bug A. FUZZ_ITERATIONS=2000 is now green (~113s) and fails
  only on genuinely new divergences; each tolerance keeps its <50% degeneracy
  guard. Default 300 unchanged (~17s).
- Reconciliation suite: drop SGR 7 (inverse) from the append-only tail. Inverse
  marks trailing blanks with an inverse-fg the serializer round-trips slightly
  differently by capture depth — a Bug-B-class serialize nuance, not seq
  reconciliation. FUZZ_ITERATIONS=1000 is now green; default 200 unchanged.
- Notes updated: every bug class is both pinned (skipped repro) and tolerated in
  its corpus; combined default runtime ~19s.

Regex uses String.fromCharCode(27) to stay oxlint no-control-regex clean.

* Keep RC update checks off perf prereleases

Co-authored-by: Orca <help@stably.ai>

* Fix snapshot DECSC register loss (Bug D) and mid-escape boundary drop (Bug E)

Bug D: the serialized screen cannot carry the VT100 DECSC saved-cursor
register, so a hidden ESC 7 followed by a post-reveal ESC 8 restored to
home and clobbered live cells. The snapshot epilogue now re-saves at the
source's saved position before the final absolute CUP
(readSavedCursorRegister + serializeWithAbsoluteCursor; the active
buffer's own register, so alt screens carry theirs). Position-only by
design; never-saved terminals are left untouched.

Bug E: a PTY read ending mid-escape leaves the sequence in the emulator's
parser, so serialize dropped it and the racing tail's continuation bytes
rendered literally after reveal (~24% of the fuzz corpus). The emulator
now tracks the unparsed trailing partial at ingest
(terminal-partial-escape-tail.ts, committed post-parse like the mouse
mirror) and ships it as TerminalSnapshot.pendingEscapeTailAnsi.
applyMainBufferSnapshot writes it LAST, after POST_REPLAY reset — any
later ESC would abort the dangling sequence. Seq accounting is unchanged:
the tail is a suffix of bytes the snapshot seq already counts, so
reconcile slicing needs no adjustment.

Fuzz suites: unskip the Bug B/C repros (fixed on this branch) and the new
D/E repros; remove the B/C/E tolerance predicates so regressions fail
loudly. Only Bug A (upstream wrap null-cell) stays tolerated + counted.
Green at FUZZ_ITERATIONS=2000 (fidelity) and 1000 (reconciliation).

* Cut the hidden-restore flood feedback loop (A) + query carve-out on drops (B)

(A) Under a foreground flood, the hidden-output-restore loop re-fetched
snapshots endlessly: each synchronous applyMainBufferSnapshot starved ACK
processing, main pinned at the in-flight cap, dropped at the pending cap,
and every droppedOutput/modelRestoreNeeded marker re-armed another
restore until the flood ended (rc.7.perf DSR timeouts).
- Restore loop: a foreground live-chunk queue overflow now abandons the
  restore immediately (the stream is outrunning snapshot fetch+replay),
  with a 3-iteration hard cap + lifecycle warn as backstop.
- Re-arm gate: drop markers/sentinels and reconcile seq-gaps on a visible
  pane during its own in-flight/just-abandoned restore no longer re-arm;
  live bytes write through and ONE deferred repaint (2s after the last
  backpressure signal) heals the gap. Hidden-pane gate semantics are
  unchanged.
- Query salvage: discarding queued restore bytes (overflow/refetch) now
  extracts DSR/CPR/DA/OSC-color queries and replays them to xterm so
  replies still flow.

(B) Main-side: dropOversizedPendingPtyData carves reply-eliciting query
sequences out of the dropped buffer (and out of post-drop latched data,
bounded) and ships them on the droppedOutput sentinel, so DSR probes
survive bulk drops. Query scanning moved to
src/shared/terminal-reply-query-extraction.ts, shared verbatim with the
renderer's hidden-startup query extraction.

* ACK terminal output at parse-drain, not dispatcher enqueue (C)

The renderer credited main's per-PTY in-flight window the moment a
pty:data chunk entered the dispatcher, so the 512KB window meant "bytes
received", never "bytes parsed". Under flood the renderer write queue
grew unbounded behind instant ACKs; main saw no backpressure, crossed
the pending cap, and bulk-dropped output (rc.7.perf DSR timeouts).

Crediting is now parse-deferred: each delivery carries a fire-once
credit (deliverPtyDataWithDeferredAck); the pane's first scheduler write
claims it (writeTerminalOutput.ackCredit) and the output scheduler fires
it when the bytes are consumed — after terminal.write in the
parse-clocked drain, or on ANY discard path (backlog cap replacement,
discardTerminalOutput, disposed-terminal drops, flush recovery).
Deliveries that never reach the scheduler (reconcile drops, restore
queueing, pre-mount eager buffer) settle at handler return, so the
invariant holds: every delivered chunk credits exactly once, parsed or
discarded. E2E ack-gate hold/release and delivery-resync semantics are
unchanged (all crediting still routes through ackPtyData).

Main-side equilibrium: with ACKs at parse cadence, in-flight becomes
true backpressure — pendingData stays near the 256KB producer-pause
watermark, far under the >=2MB drop cap, so bulk floods block the shell
(node-pty pause) instead of dropping.

* Synthesize salvaged query replies directly instead of replaying into xterm

The 10MB dev bench proved the write-back salvage insufficient: a
pending-cap drop always triggers a snapshot restore, whose replay guard
swallows xterm auto-replies and whose discardTerminalOutput races away
still-queued query writes — the salvaged DSR died both ways and the
fence still timed out.

Salvage now answers directly on the input path (immune to both): CPR
(CSI 6n) from the live buffer via transport.sendInput, DA1 with the
renderer's canned response, OSC color probes via the existing direct
responder. Rare queries (DECRQM, DA2) keep the best-effort xterm
replay.

* Fix Windows update-relaunch killing the live terminal daemon

On a Windows update relaunch the daemon can be wedged past every RPC
budget (final checkpoint flush + installer/AV disk pressure), so the 3s
health check AND the 5s session-list hello both time out while sessions
are still alive - and the launcher failed closed, killing the daemon and
every terminal session it owned.

- Adopt an unresponsive daemon whose pipe still accepts a raw
  connection; a new rejected health state keeps replacing daemons that
  answered and refused the handshake (never adoptable).
- Give Windows pid files a real startedAtMs (daemon self-reports it in
  the ready IPC message) and verify it via CIM CreationDate piggybacked
  on the existing command-line query, so the pid-recycling guard is no
  longer inert on win32.
- Only delete legacy daemon pid/token files when the pid-file process is
  provably dead; deleting a live daemon''s token made its sessions
  permanently unadoptable after a protocol bump.
- Capture agent resume records every 60s in the renderer (skipping
  unchanged records) so hard kills still leave a fresh resume record.

* Heal blank terminals when main→renderer push delivery dies (renderer-pull delivery watchdog)

Field evidence (v1.4.121-rc.0 debug snapshot, 2026-07-06): a wedged window
held 530,115 un-ACKed in-flight chars — one PTY pinned at the 512KiB per-PTY
high water plus a fresh terminal's 245-char prompt that was sent and never
consumed — while the user ran the snapshot over invoke from that same window.
Main→renderer push delivery (pty:data and every sibling channel) was dead;
renderer→main→renderer invoke was alive. Upstream precedent for
one-directional IPC death: electron#37067 (suspected Mojo pipe disconnect,
stalled as need-info). Every terminal goes blank, new terminals are born
blank, and only a renderer reload recovered.

The existing recovery layers cover the OTHER variants of this bug family and
structurally cannot reach this one:

- The xterm write-pipeline sync-throw guards, output-buffer caps, and
  probe-certified replay-guard release (#7150 family) run only after bytes
  arrive in the renderer — here they never do. (The pending cap did work as
  designed in the field: ~2.1MB pendingDroppedChars, bounded main heap.)
- Cumulative ACKs self-heal lost ACK messages and the solicited delivery
  resync reconciles verified totals (4647df86a; #7260 on main) — but the
  resync probe, the powerMonitor wake relay, and the droppedOutput restore
  markers all ride main→renderer push, the direction that is dead. The
  probe's unanswered path deliberately only logs.

This adds the missing lane, renderer-initiated and ridden entirely over
invoke — the direction the field snapshot proved alive:

- terminal-delivery-watchdog.ts: 15s heartbeat, free while output flows.
  Hot-path cost is one Map upsert per received chunk; a tick does no IPC
  unless the terminal plane was silent for the whole interval and a PTY
  still expects delivery. Two consecutive silent ticks with main reporting
  ACK-starved in-flight confirm the wedge; heals are one-shot per 60s
  cooldown so a persisting wedge cannot repaint-storm.
- pty:reportRendererDeliveryState (invoke): always max-merges the renderer's
  cumulative processed totals (a free extra repair lane for the lost-ACK
  variant); with heal:true — and only after main has itself seen ≥10s of ACK
  silence — writes off bytes the renderer provably never received
  (received ≤ acked < sent; a received-but-unparsed backpressure window is
  never written off), drops that PTY's pendingData (snapshot covers
  everything ≤ markerSeq, hidden-drop parity), credits provider flow
  control, and returns restore markers in the reply.
- The renderer re-attaches all push listeners (cures a detached-listener
  variant outright; a safe no-op against a dead channel) and routes the
  pulled markers through the existing pty:modelRestoreNeeded machinery —
  panes repaint from the main-owned buffer snapshot with zero push
  delivery involved.
- Field discrimination built in: the heal warn logs
  ipcRenderer.listenerCount('pty:data') (listener detached vs channel dead)
  with the full delivery snapshot, so the next occurrence names the root
  cause without asking the user to run anything in a console.

Repro harness: the exposeStore-gated __terminalDeliveryWatchdog hook
blackholes pty:data ahead of the dispatcher — the field failure in
miniature (no receive count, no ACK credit, no dispatch).
terminal-push-delivery-loss-recovery.spec.ts proves the wedged output
repaints while the blackhole is still engaged and live flow resumes after
release, with no reload. Unit suites pin the watchdog state machine
(zero IPC under flow, two-tick confirm, cooldown), the dispatcher reattach
seam, and the main-side write-off semantics.

Perf: nothing added to main's send/flush path; the renderer data path gains
one integer/Map update per chunk; idle cost is one ~100-byte invoke per 15s
only during total terminal silence. Terminal perf e2e suite (typing
latency, redraw freeze, output scheduler, hidden TUI restore, artificial
opencode load) passes on this change; no watchdog activity occurs under
ack-gate pressure scenarios because receive-progress gates the heartbeat.

* Expose the hidden-yet-visible delivery-gate contradiction in the debug snapshot

The v1.4.124-rc.2.perf blank-terminal field snapshot showed a different
state than the v1.4.121 transport wedge: no delivery gating at all
(ackGatedFlushSkipCount 0, in-flight 38KB, far under every cap) but TWO
ptys hidden-delivery-gated with 78MB dropped as hidden. The aggregate
counters cannot say whether the pane the user was staring at was one of
the gated ones — the one number that separates "normal background
dropping" from "main is starving a visible pane because the reveal
unmark never fired".

Add hiddenDeliveryGatedVisiblePtyCount / hiddenDeliveryGatedActivePtyCount
(overlap of the gate's hidden set with the renderer's visible/active
reports — a contradiction that must be zero) to the delivery debug
snapshot, and a once-per-minute warn when hidden-gated bytes are dropped
for a pty the renderer reports visible or active, with the full snapshot
attached. Zero cost outside the debug read and the already-dropping path.

* Unlatch the hidden-delivery gate when user input disproves a stuck document.visibilityState

macOS occlusion tracking can wedge document.visibilityState at 'hidden'
after display sleep and never fire another visibilitychange. The hidden-
delivery gate then keeps dropping renderer-bound bytes for panes the user
is looking at (field snapshot 2026-07-06, v1.4.124-rc.2.perf: 78MB dropped
across 2 pane-level-visible ptys with a fully healthy transport), and every
recovery path (window focus, system-resume relay, backlog recovery) re-ran
syncHiddenRendererPtyDelivery only to recompute the same stale predicate —
nothing could ever clear the gate. The user sees a frozen terminal; typing
echo is dropped in main; only a reload recovers.

Real user input while the document claims hidden is a physical
contradiction: keystrokes and clicks only reach a focused, on-screen
window. stale-document-visibility.ts latches that proof, runs each pane's
existing visibilitychange resync (gate unhide + hidden-output snapshot
restore), and hands authority back to the occlusion tracker on the next
genuine visibilitychange. No timers; the failure bias is safe — a wrong
latch can only restore pre-gate delivery cost, never drop bytes. Hot path
unchanged: the foreground predicate still returns on the same single
comparison while the document is visible.

tests/e2e/terminal-stuck-occlusion-recovery.spec.ts pins the wedge
(visibilityState pinned hidden -> output dropped, not painted; the
hiddenDeliveryGatedVisiblePtyCount field discriminator reads >0) and the
recovery (one Shift keypress repaints the missed output from the main-owned
snapshot, no reload, while visibilityState still reads hidden). Negative
control verified: the spec fails without this fix. Typing-latency perf
gate passes; terminal-pane unit suites 366/366.

* Add a one-paste terminal freeze report: __orcaTerminalFreezeReport()

Every field report of the frozen-terminal family so far has needed
follow-up asks (console output, main logs, second snapshots) because each
capture showed one process's counters at one instant. This makes a single
DevTools command sufficient: `await window.__orcaTerminalFreezeReport()`
returns renderer state (document.visibilityState + the stale-visibility
override, pty:data listener count, delivery-watchdog totals), main's debug
snapshot extended with a per-pty delivery table (sent/acked/pending, hidden
vs visible-set membership, last send/ACK ages, window focus flags, power
suspend/resume ages, app version), and bounded breadcrumb rings from BOTH
processes recording the transitions that matter: gate marks/unmarks,
visibilitychange and stale-visibility latches, watchdog stalls and heals,
restore markers, heal write-offs, and renderer lifecycle resets (so "user
already reloaded" is visible in the history).

Costs stay off the data path: breadcrumbs record only rare transitions into
a 100-entry ring with same-kind coalescing (a flood costs one slot per
second); the per-pty table is built only when the snapshot is read; the
per-send bookkeeping adds one Date.now() to existing accounting writes. Pty
ids are redacted to their `@@` suffix because daemon session ids embed
worktree paths. The report assembles over invoke IPC — the direction proven
alive in every observed wedge — and a failing invoke is captured as data
instead of sinking the report.

The stuck-occlusion e2e now also pins the report end-to-end: after the
wedge + keystroke recovery, the report must carry the stale-visibility
latch and gate transitions in the renderer ring, gate-mark/unmark in main's
ring, and a populated per-pty table. Suites: pty.test.ts 258, terminal-pane
1705, shared ring 5; typing-latency perf gate passes.

* perf(daemon): keep-tail thin hidden panes' stream so agent floods never bury typing (STA multi-workspace lag)

Hidden panes are exempt from pendingData flow control (main gate-drops
their bytes after ingestion), so N background agents ran unbounded ahead
on the one shared daemon->main stream socket (measured 192MB user-space
backlog) and visible-pane echo waited FIFO behind it — typing appeared
seconds late whenever several agents burst on a loaded machine
(8x512KB/s + 12 CPU spinners: p50 293ms fix-off; 12x1MB/s: 6.1s).

Mechanism (replaces producer pacing — no reveal catch-up, ever):
- Shallow socket write gate (128KB) + per-session fairness bypass bounds
  echo latency by construction; kernel-flush refill sentinel keeps held
  bulk draining at full speed (drain-only refill capped at ~8MB/s).
- Backgrounded sessions' queued output is keep-tail dropped (newest
  512KB kept, in-order dataGap replaces the middle); a ~2MB GLOBAL
  budget shrinks per-session keep-tails (floor 64KB) so a worktree
  switch never waits behind the aggregate. Reply-eliciting query bytes
  (DSR/DA/OSC probes) are salvaged from dropped spans.
- Notifications are structurally lossless: the daemon runs the same
  shared scanners main uses (bell/OSC 133/pr-link/2031) over every byte
  BEFORE drop decisions and relays facts in byte order; ordered
  background markers hand scan authority back and forth, seeded with the
  emulator's partial escape tail so a sequence split across the handoff
  neither phantom-fires nor goes missing. Titles/agent-status stay
  main-side (kept-tail convergent).
- Main: background = hidden AND no remote view subscriber (a live
  mobile/web view is never thinned); on dataGap main resets cross-chunk
  parse carries, drops the headless mobile mirror, and reuses the
  hidden-drop model-restore marker.

Wire: three new stream events, tolerated within protocol v19 (old mains
ignore unknown events; old daemons never see the trigger). Kill
switches: ORCA_DAEMON_BACKGROUND_STREAM_DROP=0,
ORCA_DAEMON_SHALLOW_SOCKET_GATE=0.

A/B (pnpm bench:multi-workspace-typing): 8x512KB/s + 12 CPU workers
p50 293ms/p90 647ms -> 15/21ms (= baseline); 12x1MB/s 6,146ms -> 20ms;
light loads unchanged; zero missing echoes. Latin hidden-restore e2e
green (probe-verified aggregate-drain root cause). New deterministic
repro harness: tests/e2e/terminal-multi-workspace-typing-latency.spec.ts
+ CPU pressure workers.

- webgl-context-loss crumb at onContextLoss, webgl-atlas-reset crumb at the

  'missed repaint'.
- wake-recovery:<source> crumb (focus/visibilitychange/system-resumed) with the
  clearGlyphAtlases decision; source in the kind so distinct triggers don't

- per-pane WebGL state (getAllPaneRenderingDiagnostics) in the freeze report.

calls in the terminal-view-attributes feature (ee540f32d, perf-branch only),
failing PR Checks 'verify' lint. Mechanical global→Number.* rewrite via
oxlint --fix; behaviorally identical. Pre-existed the latest main merge.

* fix(test): update stale terminal test stubs/expectations to current runtime

Three pre-existing perf-branch test failures (red before the latest main
merge; unrelated to it) — all stale test scaffolding lagging behind
perf-branch features, no production code changed:

- provider-dispatch.test.ts: electron mock missing powerMonitor, which
  pty.ts installPowerSignalBreadcrumbs now calls on registerPtyHandlers.
  Added powerMonitor:{on:vi.fn()} to match pty.test.ts.
- runtime-terminal-stream.test.ts: onSnapshot now receives a second
  { pendingEscapeTailAnsi } meta arg (#7329); updated the three exact-arg
  toHaveBeenCalledWith assertions.
- terminal-multiplex-escape-tail.test.ts: stubRuntime missing
  registerRemoteTerminalViewSubscriber (subscribe path calls it now, erroring
  before snapshot serialize); added the stub used by sibling multiplex tests.

* Fix hidden/parked split-pane exit stranding ghost or resurrected panes

Deterministic e2e repro of the field 'ghost blank pane' incident (a
closed/finished setup-split leaf persisted in root with no binding and
remounted as a permanently blank pane) found two teardown gaps at the
hidden-view parking boundary:

1. The kept-exit guard ('freshly split pane can lose its newborn PTY
   during setup') fired for HIDDEN panes. The hidden-delivery gate
   withholds their bytes, so a hidden split always looks output-less and
   its dead pane was kept — a binding-less ghost that dead-session
   reconcile can never reach (no PTY id to prove dead). The keep is a
   visible-failure UX; gate it on isVisibleRef and close hidden panes.

2. A PTY exit landing while the tab is PARKED reached only the parked
   watcher's exit sidecar (hosts' onPtyExit requires a mounted
   TerminalPane), which only disposed the watcher. The leaf's stale
   binding then reattached on reveal and the daemon re-created the
   exited session id as a fresh shell — silent pane resurrection. The
   sidecar now collapses the dead leaf out of the stored layout via
   detachTerminalLayoutLeaf (the observed-exit teardown's data half).

New e2e suite terminal-pane-close-layout-consistency.spec.ts sweeps
close/shell-exit at every hidden/park lifecycle phase and asserts
leaves(root) == bindings == live panes; all 7 scenarios pass. Unit
regressions added for both fixes.

NeilandOrca e33b2006f4 Remove stale max-lines lint disables from files under the limit (#7548)
110 files carried an eslint/oxlint-disable max-lines directive but are
already under the default max-lines budget (300 .ts / 400 .tsx / 600 .mjs
/ 800 test), so the suppression is dead. Removing it restores real
max-lines coverage on these files with zero behavior change.

Each removed directive had max-lines as its only rule; verified via a
full oxlint run (0 max-lines violations, 0 new errors). Diff is pure
deletions (200 lines, 0 additions) — no code touched.

NeilandOrca 46646d7ff1 chore(lint): upgrade oxlint to 1.71 + enable 7 new rules (autofixed backlog) (#6841)
* chore(lint): upgrade oxlint to 1.71 and enable 7 new rules

Upgrade oxlint 1.67.0 -> 1.71.0 (1.72 was blocked by the repo's 3-day
minimum-release-age supply-chain guard; nothing here needs it). The
bump is a no-op on the existing config.

Enable 3 error rules (backlog autofixed to zero in this commit) and
4 warn rules (surface signal without gating CI):

error (autofixed, behavior-preserving):
- unicorn/prefer-node-protocol        (~1531 sites: bare builtin -> node:)
- typescript/no-import-type-side-effects (~36: all-inline-type -> import type)
- unicorn/no-array-reverse            (19: copy-then-reverse -> toReversed)

warn (real signal, current fires are test-only/correct):
- unicorn/no-array-fill-with-reference-type  (aliasing footgun guard)
- typescript/no-unsafe-function-type         (bans bare Function type)
- unicorn/prefer-array-flat-map              (map().flat() -> flatMap())
- unicorn/prefer-regexp-test                 (.match() in bool ctx -> .test())

mobile/.oxlintrc.json extends root, so it inherits all 7; the autofix
ran from root and covered mobile/ too.

Verification (all green): oxlint 0 errors (root+mobile+aux configs),
oxfmt clean, typecheck (node+cli+web), vitest 22795 passed / 0 failed,
builds (electron-vite + web + cli) succeed. node: rewrites confirmed to
skip embedded SSH/CLI string payloads (AST-only); all toReversed sites
verified to operate on fresh copies or write-once locals.

* chore(lint): bump mobile oxlint to 1.71 so inherited rules parse

mobile/ is a standalone pnpm project pinning its own oxlint@1.67, which
lacks unicorn/no-array-fill-with-reference-type (needs >=1.70). Since
mobile/.oxlintrc.json extends the root config, mobile CI's 'cd mobile &&
oxlint' failed to parse the new rule. Bump mobile to match root (1.71).

Verified in mobile/: oxlint 0 errors, oxfmt --check clean, tsc --noEmit
pass, vitest 978 passed / 0 failed.

+3 36277801e4 Make remote hosts first class: concurrent multi-host workbench (#5071)
* Restore the outlined server card for host headers

Feedback: the bordered card with the server glyph made it clearer that
a host section is a separate machine, not just another group. Bring
that back while keeping the recent quieting: no status dot when
healthy (marks only for connecting/blocked/error/disconnected), no
'This computer' detail on the local host, and collapse/menu/count
behavior unchanged.

Co-authored-by: Orca <help@stably.ai>

* Anchor host badge to its label, indent rows under host cards

Sidebar polish from review:
- The count badge sat in dead space between the label and the
  hover-only chevron/menu; it now hugs the label like repo headers
- Rows under a host card get a left inset so projects and workspaces
  visibly belong to the machine above them
- A host whose only visible row is a collapsed repo group counted 0
  while the group badge said 9; host counts now fall back to header
  counts for groups contributing no visible items

Co-authored-by: Orca <help@stably.ai>

* Two-tier sticky headers: pinned host card above pinned group header

When scrolling inside a host section, the host card now stays pinned at
the top (z-30) while project/status group headers hand off beneath it
(z-20, offset by the pinned card height). The host is the outer
hierarchy level, so it is the most persistent context — previously the
first repo header replaced it, losing 'which machine am I on' exactly
when it mattered. The pinned card keeps its collapse/menu/warning
affordances. Handoff rules: the next host card pushes the previous one
out at the viewport top; a group pins only once it reaches the slot
beneath the host card, and a previous host's group can never pin under
the next host. Without host sections the logic degrades to the original
single-tier behavior.

Co-authored-by: Orca <help@stably.ai>

* Revert host-section row indent

The two-tier sticky host card now provides continuous 'inside this
machine' context at any scroll depth, making the static indent
redundant — and it cost 12px of sidebar width on every row while
making multi-host layouts misalign with single-host ones. Host cards
bracketing their sections plus the pinned header carry the ownership
signal on their own.

The tour panel portals into dialog/sheet content that clips overflow, but
its position was clamped against the window viewport. With the Project
field spanning nearly the dialog's full width, the panel landed past the
dialog's right edge and overflow-hidden cut it down to a sliver. Clamp
hosted panels within the host's bounds instead, so the panel flips below
the target and stays fully visible.

* Handle buffer overflows gracefully and truncate diffs fairly (#5083)

- Gracefully fall back to file-name summaries when staged diffs exceed
  node/ssh execution maxBuffer limits, preventing generation failures.
- Split oversized diffs by file and allocate budget via water-filling,
  ensuring single huge files do not starve smaller human changes.
- Clip truncated diff sections on line boundaries to avoid half-lines.

- Add unit tests verifying tooltip triggers and aria-label safety.
- Simplify memo dependencies in settings metadata and worktree palette
  by using 'useTranslation()' to handle language-change rerenders
  directly without needing 'i18n.language'.

- Pass `{{artifact_url}}` as a literal template variable to translate
  calls to prevent i18next from treating it as a dynamic placeholder.

* Fix localization reactivity in RepositoryHooksSection

Move static variables containing translation calls into helper functions

* Fix automation tabs showing a shell instead of the live agent (#5099)

* Fix automation tabs showing a shell instead of the live agent

Opening a background automation's terminal tab showed a bare shell while
the agent (Claude) kept running headless — the sidebar updated but the
pane was attached to the wrong PTY.

On first mount the restored ptyId equals the tab ptyId, and
isSessionOwnedByWorktree() returns true for it, so connectPanePty routed
the still-live eagerly-spawned PTY into the daemon-reattach branch
(transport.connect({ sessionId })), which spawns a fresh shell and
orphans the live agent PTY instead of adopting it via attach()+replay.

Part A: gate the deferred reattach on the absence of a live eager buffer.
A live eager buffer means the PTY is a still-running local session to
adopt (attach + replay), not a daemon session to re-connect. Daemon
reattach and remote PTYs are unaffected (gated on the eager buffer).

Part B: publish never-mounted background automation tabs into the runtime
graph (gated on a live eager buffer) so the live agent PTY binds to its
real tab instead of surfacing as an orphan `pty:<id>` terminal — fixing
`orca terminal list`, the CLI, and automation session-reuse.

Adds a characterization test (fails on the old code, passes now) and a
runtime-graph publish test.

when combined with CJK text, while adjusting Korean particle spacing.
Also add overrides to prevent network proxy settings from being
mistranslated as "Agent".

* Preserve repo terminology in English and localize source control labels

Treat "repo" and "repos" (and their capitalized forms) as brand terms
that should remain in English/Latin across CJK and Spanish locales.
Update translation files and policies to replace translated words like
"repositorio" or "リポジトリ" with "repo"/"repos", and fix an issue where
latin brand terms could be incorrectly matched as substrings in larger
words during cleanup.

Additionally, externalize and localize the "Staged Changes", "Changes",

* Evaluate only the selected save target instead of checking all available targets, as the action only writes to the selected target.
* Update daemon PTY adapter test fake PID to prevent collision with real host OS processes during runtime directory lookups.

* fix: remove unsupported agent launch defaults (#5185)

* Update Chinese and Japanese translations for worktrees and fixes (#5187)

- Correct awkward Chinese translation of "fix" ("使固定") to "修复" and "基本的" to "主工作树" (main worktree).
- Improve Japanese translation of "fix" from physical repair ("修理") to software correction ("修正").

* Embed hosted review creation composer directly in Checks panel (#5140)

* Embed hosted review creation composer directly in the Checks panel

- Replaces the modal pull request/merge request creation dialog with an
  inline composer embedded in the empty state of the Checks sidebar.
- Extracts and moves pull request generation state to a dedicated store
  slice so AI-generated details are persisted across sidebar unmounts.

* Fix hosted review composer feedback

* Combine file search and file explorer right sidebar tabs (#5182)

Unifies file discovery and tree navigation under a single Explorer domain, simplifying the right sidebar activity bar and reducing tab clutter.

* Replaces the standalone 'search' activity bar tab with a nested 'search' subview inside the File Explorer tab
* Introduces 'rightSidebarExplorerView' ('files' | 'search') state to manage the active subview inside the Explorer
* Adds a search button to the File Explorer toolbar and a back button to the search subview for seamless transition
* Exposes 'showRightSidebarFiles' and 'showRightSidebarSearch' store actions to route and seed search queries/include patterns
* Adapts file explorer keybindings, git status polling, and external workspace watchers to respect the active subview
* Maps legacy persisted search tab state to the new explorer search view for backward compatibility

* release: v1.4.61-rc.1

* Add multi-repo folder workspaces (v1) (#5172)

Jinwoo HongandOrca a638215729 fix(pty): release ptmx fd on natural exit + defuse SIGHUP-to-recycled-pid (#1327)
* fix(pty): release ptmx fd on natural exit + defuse SIGHUP-to-recycled-pid

Daemons accumulated ptmx fds over time because node-pty's UnixTerminal
only releases the master fd when destroy() runs. On the natural-exit
path (the common case — user closes a tab, shell runs `exit`) nothing
ever calls destroy(), so the fd leaks until GC. On macOS this
eventually hits kern.tty.ptmx_max=511 and all new terminals fail to
spawn.

Fix: release the fd synchronously on every teardown path (natural
exit, explicit kill, stale SSH spawn, daemon shutdown) and close the
concurrent SIGHUP-to-recycled-pid hazard inside node-pty's
UnixTerminal.destroy().

- src/main/daemon/pty-subprocess.ts: synchronous POSIX proc.kill
  neutralization inside proc.onExit; dead guards on forceKill/signal
  so they never target a reaped-and-possibly-recycled pid
- src/main/daemon/session.ts: new disposeSubprocess() for already-
  exited sessions (fd release only, no SIGKILL) — avoids sending
  SIGKILL to a recycled pid during daemon shutdown
- src/main/daemon/terminal-host.ts: dispose loop routes on isAlive —
  live sessions get forceKillAndDisposeSubprocess (SIGKILL + fd
  release), exited sessions get disposeSubprocess (fd release only)
- src/main/providers/local-pty-provider.ts: same POSIX kill
  neutralization at top of onExit for the legacy local path
- src/relay/pty-handler.ts: same neutralization in wireAndStore;
  disposed flag guards all public entry points; dispose() uses
  SIGKILL (not SIGTERM) before destroy since the relay is exiting;
  killTimer fallback + immediate-shutdown + stale-spawn cleanup all
  call disposeManagedPty + ptys.delete so wedged children (D-state,
  bad NFS) can't leak map entries against the 50-PTY cap

Windows is exempt everywhere — WindowsTerminal.destroy IS a kill()
call internally (closes the ConPTY agent), so neutralizing would
turn destroy into a no-op and leak the agent.

See docs/fix-pty-fd-leak.md for the full design.

* fix(pty): patch node-pty native off-by-one leaking /dev/ptmx per spawn

node-pty 1.1.0's pty_posix_spawn on macOS walks low_fds[0..2] in an
allocation loop that breaks at the first fd >= STDERR_FILENO, then
cleans up via `for (; count > 0; count--) close(low_fds[count])`. In
the typical case (break at count=0) the cleanup body never runs and
low_fds[0] — a /dev/ptmx handle — leaks per spawn. Fixed upstream in
microsoft/node-pty af053f2 (PR #882), not in any 1.1.0 release.

Backport the 3-line cleanup-loop fix as a pnpm patch. E2E validated
against a dev daemon: 200 spawn/kill cycles kept the daemon's ptmx
fd count flat at baseline; prior runs reproduced linear 1-per-spawn
growth. Also documents the native root cause as a status addendum in
docs/fix-pty-fd-leak.md — the JS-side destroy() discipline previously
landed is still load-bearing for the SIGHUP-to-recycled-pid hazard and
for synchronous fd release on daemon shutdown.

* fix(pty): capture stable kill spy ref in pty.test.ts

destroyPtyProcess reassigns proc.kill = () => {} on POSIX to defuse
the SIGHUP-to-recycled-pid hazard (see docs/fix-pty-fd-leak.md). After
that reassignment, proc.kill.mock is undefined and the assertions
crashed in CI. Capture a stable reference to the vi.fn() before it
gets reassigned.

* Wip

* fix(terminal): make split-pane cwd resolution reliable on macOS

Coalesce and cache per-pid lsof calls in the main process, and raise the
renderer's IPC timeout to 1s so cold lsof lookups (typically 100–500ms,
occasionally ~1s) don't fall back to the worktree root.

* chore: remove stray screenshot and harden daemon getCwd test

- drop orca-before-split.png accidentally committed in the Wip commit
- accept null OR string from getCwd in the daemon test, since the new
  terminal-host fallback calls resolveProcessCwd(pid) and the mock pid
  55555 could resolve against a live process on CI
